PROCUREMENT SPECIFICATIONS DELTA MODEL DSC 1500 PORTABLE BEAM - CRASH CERTIFIED BARRIER SYSTEM

SYNOPSIS This Procurement Specification defines a CRASH CERTIFIED- PORTABLE Beam BARRIER SYSTEM- DELTA Model DSC 1500. The system has been tested in full scale configuration at an independent testing laboratory and certified to meet ASTM F2656-18a M30 (K4). Gross Vehicle Weight: 15,000 pounds (6800 kg) Crash Speed: 30 mph/49kph The DSC 1500 is configured for expedited deployment and, as needed, retrieval and relocation. The DSC 1500 is a self-contained beam type barrier with a free passage between buttresses of 16 feet, (192 inches) (4.9 M), and no vehicle height restrictions. This Barrier System can be sited on existing concrete or asphalt roadways or verges; level compacted soils or a combination of these. No excavation or sub-surface preparation is required. The Barricade is deployed after being towed to the site and then lowered into position by means of a self-contained hydraulic hoist. No hand cranking required. Once sited the wheels are moved away. Estimated deployment time less than 10 minutes. The standard system has a BATTERY OPERATED Hydraulic Power Unit, maintained and recharged from either a Solar Array, an Internal Battery Charger (operated on a local power source), a Field Interchangeable Rechargeable Battery Pack or from other local low voltage sources. The control point can be at the Barrier, or at an adjacent control site, or by a hand held control module on a 'plug-in' umbilical cable. The Hydraulic Power Unit can be located on the Barricade or positioned remotely. A DELTA Hydraulic Power Unit operated on locally supplied power can be specified in locations where suitable local power is available. Both the Locally Powered and the Battery Powered Hydraulic Pumping Units can be sized to provide pass-through rates suitable for most inspection and identification station requirements. Available operating modes include, full automatic, remote-hard line, remote-radio, card reader, key switch, local guard push button station, master(s) and slave(s) control panels... etc. - or by combination thereof.

13. DISCLAIMER Please note - careful consideration must be devoted to the selection, placement and design of a Vehicle Barrier. Just as in the case of any traffic system, perimeter security device or security gate that blocks a roadway or drive, care must be taken to ensure that approaching vehicles as well as pedestrians are fully aware of the Barriers and their operation. Proper illumination, clearly worded warning signs, auxiliary devices such as semaphore gates, stop-go signal lights, audible warning devices, speed bumps, flashing lights, beacons, etc. should be considered. Delta has information available on many such auxiliary safety equipment not specifically listed herein. It is strongly recommended that an architect and or a traffic and or safety engineer be consulted prior to installation of a Barricade system. Delta will offer all possible assistance in designing the operating equipment, controls and the overall system but we are not qualified nor do we purport to offer either traffic or safety engineering information. This device is not suited for pedestrian control. 14.
